QUETTA - Three tankers, carrying fuel for Nato forces in Afghanistan, were damaged on Kumri Bridge, some 10 kilometres from Dhadar area of Bolan Wednesday. The Levies Forces officials said the Kandhar-bounded tankers caught fire when unknown armed motorcyclists sprayed a volley of bullets as the drivers did not followed their signal to stop. However no one injured in the attack. The attackers, in fact, avoided shooting fires on the drivers. Their (assailants) target was to damage the Nato supplies in the tankers, Bolan Tehsildar Muhammad Ismail said. The Levies Force registered a case and launched a hunt for the attackers.
